looking for films

A local film festival is trying to find out where to get the following films
to show at their festival:
Royal Warriors (with Michelle Yeoh)
Come Drink With Me (with Cheng Pei Pei)
Black Cat (with Jade Leung)
I can find these on OCLC and through Facets, but am not sure where to go
from there. I'm new at this process, and any information would be a great
help.

I also have a patron looking for a video entitled Umabatha: The Zulu
Macbeth. I can find a book with that title on OCLC, but no indication
anywhere that there was ever a video. However, he showed me the video box
with that title on it, so it was out there somewhere at one time. He said he
bought it at a local thrift store, but someone had taped over it, and now
he's curious.
